2.Effect of Prior Cataract Surgery on the Clinical Outcome of Selective Laser Trabeculoplasty.
Journal of the Korean Ophthalmological Society 2015;56(6):911-916
PURPOSE: To compare the efficacy of selective laser trabeculoplasty (SLT) in phakic and pseudophakic eyes in primary open-angle glaucoma. METHODS: Charts of 55 phakic eyes and 24 pseudophakic eyes that underwent 360-degree SLT were retrospectively reviewed. Intraocular pressure (IOP) was measured before SLT and 1 week, 1, 3, 6, 9, 12, 18 and 24 months after SLT. Treatment success was defined as IOP reduction > or = 20% without additional medications, laser or glaucoma surgery. Mean IOP change, mean percentage of IOP reduction and success rates of phakic and pseudophakic eyes were compared. RESULTS: Mean percentage of IOP reduction after SLT at 1 week and 1, 3, 6, 9, 12, 18, and 24 months were 18.8%, 23.9%, 24.6%, 23.3%, 24.0%, 22.1%, 20.8%, and 17.9%, respectively, in the phakic group and 15.7%, 22.3%, 23.7%, 25.3%, 25.6%, 25.2%, 21.9%, and 19.3%, respectively, in the pseudophakic group. Success rates were 57.6 +/- 11.9% in the phakic group and 61.3 +/- 10.4% in the pseudophakic group. No statistically significant differences in IOP change, percentage of IOP reduction, and success rates were observed between the groups at each time point after SLT (p > 0.05). CONCLUSIONS: Application of 360-degree SLT appears an efficient treatment option for the management of phakic and pseudophakic open-angle glaucoma. Evaluating the success of SLT 1 month postoperatively may be premature.

3.A Case of Central Serous Chorioretinopathy after Glaucoma Filtering Surgery.
Journal of the Korean Ophthalmological Society 2014;55(12):1895-1900
PURPOSE: To report a case of central serous chorioretinopathy development after glaucoma filtering surgery and spontaneous resolution in a patient with a history of central serous chorioretinopathy in the contralateral eye. CASE SUMMARY: A 46-year-old male with a history of chronic uveitis in both eyes presented with uncontrolled intraocular pressure (IOP) in his left eye. Initial IOP was 34 mm Hg in his left eye. On preoperative evaluation, central serous chorioretinopathy, which was diagnosed in another clinic 1 month prior, was observed in his right eye. Slightly pale optic disc and retinal nerve fiber layer defects were noted in the left eye. However, macular abnormalities were not observed in the left eye. Trabeculectomy and peripheral iridectomy using mitomycin C were performed in the left eye. The patient was prescribed triamcinolone 8 mg daily for 4 days to reduce the post-surgical inflammation. On postoperative day 4, IOP in the left eye was 7 mm Hg and newly developed central serous chorioretinopathy was noted. On follow-up, IOP was maintained at 7-10 mm Hg and central serous chorioretinopathy disappeared 7 months postoperatively. CONCLUSIONS: When clinicians consider performing an ophthalmological procedure in a patient with a history of central serous chorioretinopathy in the contralateral eye, careful observation of central serous chorioretinopathy development is recommended.

Purpose: Cystoscopy, as with other endoscopic procedures, is a fearful and painful for the majority of patients. To this reduce fear, pain and discomfort, the routine administration of sedative drugs, such as midazolam and propofol, is widely accepted for a gastrointestinal endoscopy. There have also been some studies on midazolam anesthesia during cystoscopy. However, the effects and safety of propofol anesthesia during cystoscopy have not been established. Therefore, the effects and safety of propofol anesthesia during cystoscopy were investigated in this study. Materials and Methods: 200 male patients were divided into 2 groups: Group A consisted of 80 patients sedated using 1mg/kg propofol IV, and group B consisted of 120 patients who received normal saline IV instead of propofol. All patients received 90mg diclofenac IM for pain control. There were no significant differences in the ages and weights between the two groups. The vital signs and oxygen saturation were monitored before, during and after the cystoscopy. The degree of pain and satisfaction of the patients and urologist were measured. Results: The pain scales were significantly reduced in group A compared to group B. Group A patients and the operator were also significantly more satisfied than those in group B. Although the blood pressure, pulse rate or respiratory rate changed during the cystoscopy, they were not clinically significant and there was no need for additional treatment. 12 patients in group A showed temporary hypoxia; however, they were treated with oxygen administration and recovered within several minutes. Conclusions: Propofol anesthesia during cystoscopy can be performed safely and effectively as an outpatient procedure, as long as there is adequate preparation and monitoring.

18-Fluoredeoxyglucose position emission tomography and computed tomography (F-18FDG PET/CT) scanning has been useful in the evaluation of malignant disorders and has been extensively used in cancer screening.1 However, F-18FDG uptake was not found to be specific for cancer diagnosis. Here, we describe increased F-18FDG uptake on PET/CT caused by extensive tuberculous lymphadenitis in a 62-year-old woman with malignant melanoma.

Prediction of individual outcome after cardiopulmonary resuscitation is of major medical, ethical, and socioeconomic interest but uncertain. We experienced the case thats the patient got complete neurologic recovery after the 123th day firm cardiac arrest, who had been suspected to go with poor prognosis because she got the findings of Glasgow Coma Scale 4, severe diffuse encephalopathy on encephalogram and generalized tonic-clonic seizure at the 4th day. Recently, a 29 year-old women who sustained from respiratory arrest induced presumably by sedative and anticonvulsant therapy for control of seizure that happened during local lidocaine anesthesia far mamoplasty was transfered to our emergency medical center from local private plastic office. Arrest time was about 20 minutes. On hospital arrival, she had a pulseless bradyasystole and no respiration, but spontaneous circulation was restored at 10 minutes artier CPR started. We started cerebral oriented resuscitation including mild hypothermia(34degrees C), hemodilution, calcium channel blocker infusion. On hospital day 4, patient's glasgow coma scale(GCS) was 4. On hospital clay 7, Brain Magnetic Resonance Imaging(MRI) showed high signal intensity on T2WI, involving the bilateral basal ganglia. After contrast administraton, marked enhancement can be seen at the lesion site. Patient's glasgow coma scale(GCS) increased step by step to 5 on 8th day, 7 on 14th day, 10 on 15th day, 13 on 17th day, 15 on 20th day. 40 days later the patient was discharged with minor neurologic abnormality including hand tremor, dysphonia, amenorrhea and Mini Mental State Examination(MMSE) score(26). Long-term Follow up revealed that all neurologic functional abnormality inducting hand tremor, dysphonia, amenorrhea and MMSE score(26) is completely recovered on 123th day after episode of cardiopulmonary arrest.

BACKGROUND AND SIGNIFICANCE: Because of the diverse clinical and radiologic manifestations of Neuro-Behcet disease, it is sometimes difficult to differentiate with multiple sclerosis or tumorous condition. We report two cases of Neuro-Behcet disease underwent by stereotaxic biopsy showing vasculitis without any evidence of malignancy, initially misdiagnosed as solitary tumor and metastatic tumor, respectively. CASE: A 35-year-old male admitted due to right hemiparesis. Brain CT showed low density mass shadow in left thalamus. Under the impression of low grade astrocytoma, stereotaxic biopsy was performed. Dense perivascular lymphocytic infiltration with petechial microhemorrhage mixed with hemosiderin pigment was noted in thalamic region. The other patient (male, 44yrs old) admitted due to seizure. On MRI, there are multiple inhomogenous signals on right occipital and left frontal lobe and left thalamus. Under the impression of metastatic tumor, work-up about the primary tumor was done without any positive findings. To determine the primary focus, stereotaxic biopsy was performed. Only reactive gliosis and mild perivascular lymphocytic infiltration was noted in pathologic specimen. With the retrospective careful history taking and follow-up image study, two patients were confirmed as having a Behcet's disease.

BACKGROUND/AIMS: In HCC with low AFP. we have to use repeated imaging study to evaluate residual viable rumor or recurrence after TACE ( transarterial chemoembolization). We performed the study to know that sICAM-1 in HCC can be a tumor marker of diagnosis and has cor relation with tumor size or clinical staging. The results were compared with PIVKA- , an another tumor marker of HCC. METHODS: Previously untreat ed 39 pat ients with HCC were evaluated. Serum sICAM- 1, AFP and PIVKA-II were measured by EIA, immunoradiometric assay and EIA, respectively. Tumor size were meas ured by abdominal CT and angiogr aphy. RESULTS: Range of sICAM- 1 levels with HCC patients were 189.0 to 983.6 ng/ mL, and mean value was 668.3+- 254.4 ng/ mL. Thirty four of the 39 patients (87.2%) with HCC showed sICAM- 1 levels higher than 306.4 ng/ mL (mean of 131 healt hy controls + 2SD level). Range of PIVKA-II level with HCC patients were 25.3 to 2,779.3mAU/nL, and mean value was 1,340.1+-1,091.1mAU/mL. seven of the 39 patients(94.9%) with HCC showde PIVKA-II levels higher than 40mAU/mL. Range of AFP levels with HCC patients were 4.2 to 57,520ng/mL, and mean value was 4,215.6+-10,807.2ng/mL. 10 patients (26%) showed AFP lower than 20ng/mL, and 17 patients(44%) were AFP lower than 100ng/mL. All of the 17 patients with alphaFP lower than 100ng/mL had s ICAM-1 levels more than reference range (mean of 131 healt hy cont r ols + 2 SD level), and PIVKA-II levels also more than reference range. Positive correlation was observed between PIVKA-II level and tumor size in 18 patients without vascular invasion. Accor ding t o HCC clinical staging, 10 patients (25.6%) belonged clinical stage II. 5 pat ients (12.8%) III, 24 pat ients (61.5%) IV. Both of PIVKA-II and sICAM-1 levels of stage showed significantly higher than stage II. PIVKA-II showed more positive correlation with tumor size and clinical stage than sICAM- 1. No correlation was found between AFP and sICAM-1, and positive correlation was AFP and PIVKA-II. CONCLUSION: In HCC patients with low AFP, sICAM-1 and PIVKA-II correlated with tumor size and clinical stage. sICAM-1 and PIVKA-II may be a useful marker of diagnosis. So, we need to further study to evaluate whether sICAM- 1 and PIVKA-II can be used as a marker of disease progression or prognosis.

Journal of the Korean Society of Medical Ultrasound 2011;30(1):13-18
PURPOSE: To evaluate the imaging findings of a traumatic dissection of subcutaneous fatty tissue and the treatment. MATERIALS AND METHODS: Fifteen lesions from 13 patients treated by sonography were investigated in our study. The lesions were treated by aspiration only, aspiration followed by steroid injection, and by surgical procedure. Based on the treatment, five factors such as location, size and extent of the lesions, nature of the contents, and treatment effectiveness were assessed. RESULTS: A total of 6 lesions in the thigh, 4 in the leg, 3 in the knee, and 1 each in proximal forearm and flank. All lesions were found in subcutaneous fatty tissue with an average size of 8.9 cm. The nature of the contents was serous (n = 2), hemorrhaging (n = 9), and an abscess (n = 1). Without treatment, three lesions disappeared. Five of the 7 lesions vanished after being treated by aspiration. Only one out of three lesions disappeared when they were treated by steroid injection after aspiration. The three hemorrhaging lesions disappeared after operation, but one serous lesion remained. CONCLUSION: Dissection of subcutaneous fatty tissue represents a cystic mass with serous fluid or hemorrhage. The effectiveness of lesion treatment may relate to the location, size, and content of the lesion.
